The frequencies used by cordless phones are:

     Channel     Base      Handset
        1        46.610    49.670
        2        46.630    49.845
        3        46.670    49.860
        4        46.710    49.770
        5        46.730    49.875
        6        46.770    49.830
        7        46.830    49.890
        8        46.870    49.930
        9        46.930    49.990
       10        46.970    49.970

Both side of a phone call can be heard on the base frequency, on the
handset frequency only the owner (or user) of the cordless phone can
be heard.
